Ultrasonic Transducer Kits

The Ultrasonic Transducer Kit (UTK) has been developed to teach the principles and applications of low power ultrasound transducers. The UTK contains a number of different types of ultrasound transducers, hardware that can be interfaced to these transducers, and a variety of test pieces. The courseware introduces the principles behind the main topics of interest, which are supported by assignment work using hardware from the kit. The courseware and assignments are supported by MATLAB® programs.

Curriculum Coverage
• Propagation of ultrasound through a medium
• Design and calibration of ultrasound transducers
• Wave propagation modes (including longitudinal, shear and surface wave propagation modes)
• Plate waves, measurement of material properties
• Applications in inspection, sensing systems & industrial monitoring.

The content of the Ultrasonic Transducer kit is grouped in two areas:

The first addresses transducers and the physical principles behind their application and operation. The second addresses some of the applications of ultrasound and ultrasound transducers.

The Kit comprises:

Main board: contains the amplifiers and drivers for the other components of the kit.

Basic transducers: one contact transducer with a delay line, two variable angle transducers, two fixed angle wedges (70º & 35º and 55º).

Test pieces: steel and aluminium test pieces with fixed angle transducers attached, perspex test piece with fixed angle and PVDF transducers; optional copper and brass test pieces with fixed angle transducers attached.

Test board: for mounting the test pieces during experiments.

Test block: for transducer calibration and to demonstrate various applications of ultrasonic inspection.

Vibration and SAW oscillator board: with the hardware required for experiments: the use of acoustic emissions in machine monitoring and temperature measurement using SAW crystals.

Documentation and software: The kit is completed with a CD providing the documentation as PDF files and a number of MATLAB® programs to support the material.

The UTK is available as basic and advanced kits:

Basic kit 41-005
